A process for producing a profile from flat metal strip

A process for producing a profile (8) having a different thickness having cross-section of flat metal strip (7) by means of roll forming by using a pair of rollers (2.1, 2.2) on at least one side of the metal band (7), a first groove is formed at least by following roller pairs (3.1, 3.2; 4.1, 4.2) is broadened with increasing recess width to an area with reduced material thickness (12.2 12.1), characterized in that adjacent to the at least one recess arranged regions of the flat metal strip in front (7) and / or during an engagement of a roller pair (2.1, 2.2; 3.1, 3.2; 4.1, 4.2) are bent.
